CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of priority of U.S. provisional application number 61/775,639, filed Mar. 10, 2013 the contents of which are herein incorporated by reference.

BACKGROUND OF THE INVENTION

The present invention relates to food packaging and, more particularly, to an apparatus for packaging food with dry and moist portions so that such portions remain separated and fresh.

Typically, sandwiches are made to be eaten later, sometimes days later. Currently, a variety of sandwiches have wet fixings, such as lettuce, tomato, salad dressing, oil, mayonnaise, deli meats and the like, whose moisture content would transmit to the dry fixings, such as bread products, making them soggy and otherwise unappetizing. Previous attempts at separating the wet fixings from the dry fixings involved cumbersome, bulky apparatus. Alternatively approaches involved packaging systems requiring the user to dump out the wet fixings whereby mandating an unnecessary, unsightly and unappetizing step for all to witness immediately before the user eats the packaged food.

As can be seen, there is a need for a packaging system that keeps the dry fixings dry and the wet fixings fresh by separating them with a barrier that is easy to remove without being unnecessarily unappetizing and with good taste.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

Broadly, an embodiment of the present invention provides a barrier sheet. The barrier sheet may have a first half and a second half. The second half may include a perforation bisecting the second half into two approximately equal quarters. Each of the two quarters may form a pull tab near the rectangular corners. A user may easily and conveniently assemble a food product having at least one wet fixing, a first portion of dry fixings and a second portion of dry fixings, whereby the barrier sheet sandwiches the at least one wet fixing between the first and second portion of dry fixings: the user may place the second half in contact with the first portion of the dry fixings; then place the at least one wet fixing in contact with the opposing side of the second half; then fold the first half so that the barrier sheet may sandwich the at least one wet fixing; and finally place the second portion of dry fixings in contact with the opposing side of the first half. When ready to eat, the user may grasp the pull tabs and evenly tear apart the second half along the perforation so that the dry fixings and the at least one wet fixing do not adhere to the barrier sheet as the second and first half may be removed from the food product, whereby the dry fixings remained as dry as when the food product was made.

In certain embodiments, the packaging system may include a container with two compartments, wherein each compartment may be formed by a horizontal portion and a pair of side walls, a back wall and a front wall extending perpendicularly therefrom. The back walls may be connected by a hinge segment so the container may pivot from an open position to a closed position. The pair of side walls may form tear slots dimensioned to slidably receive portions of the barrier sheet, so that the wet fixings and the portion of the dry fixings may be combined within the container may be in the closed position.

Referring to FIGS. 1 through 10, the present invention may include a packaging system 100. The packaging system 100 may include a barrier sheet 16 and a container 56. The barrier sheet 16 may be made of flexible, non-permeable material having two opposing long edges 42, a rear edge 43 and a front edge 44 defining a first half 46 and a second half 48. The first half 46 and the second half 48 may be approximately the size and shape of a flattened slice of bread. The barrier sheet 16 may form a pair of pull tabs 20 along the two long edges 42 as illustrated in FIG. 2. The perforation 18 may extend from the front edge 44 of the second half 48 to near the first half 46 so as to bisect the second half 48 into two quarters 34. In certain embodiments, the perforation 18 may coincide with the middle of a food product, such as a sandwich.

The container 56 may include a first compartment 50 and a second compartment 52. Each compartment 50, 52 may be defined by a horizontal portion 24 and a pair of side walls 60, a back wall 62 and a front wall 58 extending from the horizontal portion 24, wherein the pair of side walls 60, the back wall 62 and the front wall 58 define an open portion opposite the horizontal portion 24.

The front walls 58 may extend from the horizontal portion 24 to terminate at a lip edge 54. The back walls 62 may be pivotably joined along a hinge section 26 so that the compartments 50, 52 pivot from a closed position to an open position. Each of the pair of side walls 60 on each compartment 50, 52 may extend from the horizontal portion 24 to terminate at a plurality of slot edges 70. When in the closed position, the plurality of slot edges 70 may form two tear slots 32, one on each side wall 60 of the container 56. The tear slots 32 may be dimensioned so as to slidably receive a portion of the barrier sheet 16 and so that the opposing pull tabs 20 may protrude from the opposing tear slots 32.

The first compartment 50 may include a locking aperture 30 along the front wall 58 near the lip edge 54. The second compartment 52 may include a locking latch 28 along the opposing front wall 58 near the lip edge 54. The locking latch 28 may form a male tongue that extends above the lip edge 54. The locking aperture 30 may be dimensioned to receive the male tongue of the locking latch 28 therein so that the first compartment 50 and the second compartment 52 may be removably attached in the closed position.

A method of using the present invention may include the following. The packaging system 100 disclosed above may be provided. A user may easily and conveniently assemble a food product having at least one wet fixing 12, a first portion of dry fixings 10 and a second portion of dry fixings 14, whereby the barrier sheet 16 sandwiches the at least one wet fixing 12. The user may place the second half 48 in contact with the first portion of the dry fixings 10, such as a slice of bread, so that the perforation 18 coincides with the middle of the slice of bread. Then the user may place the at least one wet fixing 12 in contact with the opposing side of the second half 48, as illustrated in FIG. 3. Then the user may fold the first half 46 so that the barrier sheet 16 may sandwich the at least one wet fixing 12. Then the user may place the second portion of dry fixings 14 in contact with the opposing side of the first half 46 so as to sandwich the first half 46 between the second portion of dry fixings 14 and the at least one wet fixing 12, thereby keeping the at least one wet fixing 12 isolated from the dry fixings 10, 14 so that the dry fixings 10, 14 do not become soggy.

When ready to eat the food product, the user may first remove the first half 46 from the food product. In certain embodiments, the user may slide the first half 46 from between the at least one wet fixing 12 and the first portion of dry fixings 10. Alternatively, the user may remove the first portion of dry fixings 10 so as to peel the first half 46 from the food product. Then user may grasp the pull tabs 20 and evenly tear apart 22 the second half 48 along the perforation 18, as illustrated in FIG. 5, so that the dry fixings 10, 14 and the at least one wet fixing 12 do not adhere to the barrier sheet 16 as the second half 48 may be removed from the food product. In certain embodiments, the user may remove the second half 48 before removing the first half 46. In certain embodiments, the plurality of pull tabs 20 may be formed along the rear edge 43 so that a user may tear apart the first half 46 in a similar fashion as the second half 48 is torn apart 22 herein.

In certain embodiments, the user may utilize the container 56 to preserve the freshness of the food product. In the opened position, the user may place the first portion of dry fixings 14 on the horizontal portion 24 of the first compartment 50. The user may place the second half 48 in contact with the first portion of the dry fixings 14, such as a slice of bread, so that the perforation 18 coincides with the middle of the slice of bread. The user may position the second half 48 so that each of pull tabs 20 protrudes from adjacent tear slots 32. Then the user may place the at least one wet fixing 12 in contact with the opposing side of the second half 48. Then the user may fold the first half 46 so that it may sandwich the at least one wet fixing 12. Then the user may place the second portion of dry fixings 10 on top of the first half 46, thereby keeping the at least one wet fixing 12 isolated from the dry fixings 10, 14 so that the dry fixings 10, 14 do not become soggy. Then the user may pivot the container 56 from the open position to the closed position so as to removably secure the male tongue of the locking latch 28 within the locking aperture 30 in the closed position.

When ready to combine the wet fixings 12 with the dry fixings 10, 12 of the food product, the user may grasp the pull tabs 20 and evenly tear apart 22 the second half 48 along the perforation 18, as illustrated in FIG. 10, so that each quarter 34 slides through the adjacent slot 32, thereby combining the food product while the container 56 may be in the closed position. In certain embodiments, the user may tear apart 22 the second half 48 while the first compartment 50 rests on a supporting surface, or when the second compartment 52 rests on the supporting surface.
